How to use differential temperature setting on an analyser

[jamscunny]

I was curious on how to use this setting as regards to finding out if a boiler is over heating or not working up to standard.

I assume when hot water cycles or cuts out to use this, but im unsure of where to attatch the clamps and what temperatures to look out for when there is a problem.

You need to attach sensors to both flow and return.The differential is then obvious.Manufacturers have their own limits on temp diff but generally under 20*C for most boilers is a rule of thumb.

Iv seen it where the clamps get put inside the boiler, just wondering what this checks???

are you a gas fitter??

First two posts are talking about different things!

You can use a diff thermostat to measure the difference between CH flow/return, plate HE flow/return and you can also use it to see the rise in DHW in/out ( what is what the OP was alluding to ).

CPA I is best discussed in the CC.

Not being funny, but if you need a differential thermometer to figure out if a boiler is overheating or not, you are a long way from running a business on your own.
